Question

if producers have 100% of the energy source in this model, then what percentage of energy, which originated from the producer, does a third level consumer have? 10.0% 0.01% 100% 0.10% 1.00%

Explanation:

Step1: Energy transfer rule

In an energy pyramid, about 10% of energy is transferred from one trophic level to the next.

Step2: Calculate energy for first - level consumer

If producers (first trophic level) have 100% energy, first - level consumer (second trophic level) has \(100\%\times10\% = 10\%\) energy.

Step3: Calculate energy for second - level consumer

Second - level consumer (third trophic level) has \(10\%\times10\%=1\%\) energy.

Step4: Calculate energy for third - level consumer

Third - level consumer (fourth trophic level) has \(1\%\times10\% = 0.1\%\) energy.

Answer:

0.10%
